| 摘要 |
The invention relates to an arrangement comprising a current sensor, containing a bypass-branch (3) which is electrically connected in a parallel to a defined section of the current conductor (1) and a current probe (5) for measuring the current in the bypass-branch (3), a fixed dividing ratio for the current passing therethrough existing between the bypass-branch (3) and the bridged section of the current conductor (1). The dividing ratio and the electric resistance of the bypass-branch (3) are relatively high in comparison to the resistance of the bridged section of the current conductor (1), whereby the contact resistances (Rk) between the current conductor (1) and the bypass-branch (3) are negligible in relation to the resistance (RBY) of the bypass-branch (3). |
